new and useful Improvements in Printing- Recorders, of which thefollowing is a specification.

My invention relates to that class of print ing-recorders in whichnumbers are printed from a series of type-wheels arranged side by side;and my invention consists of devices,

' fully set forth hereinafter, for permitting the type-wheels to bearranged in juxtaposition while operated from separated keys forprinting only from those wheels which contain the figures in the sum tobe indicated, and for automatically effecting the adjustment of thewheels, locking them in position for operating the type, and severingthe paper.

In the accompanying drawings, Figure 1 is a side elevation of part of amechanical calculator, showing my improved recorder combined therewith;Fig. 2, a similar view showing parts of the machine in a differentposition. Fig. 3 is a plan view of the recorder and actuating-levers.Figs. 4 and 5 are separate elevations looking in the direction of thearrow a, Fig. 1, and showing the recorder and devices for automaticallysetting and locking the levers.

The recorder consists of a series of notched wheels J, turning upon ashaft K, and each wheel having a series of figures from 0 to 9, Figs. 4and 5, upon the periphery constituting printing-type. These wheels maybe set in position or actuated by any suitable actuating devices notnecessarily connected with this feature of my invention, but, as shown,each wheel is provided with a pinion 9 upon the side, gearing with therack h of the lever L, hung to a shaft 0 and connected with a lever B,each lever B being controlled in its movements by a series of keys D ina manner and through devices which need not be here described, as theyconstitute no part of this invention and are fully set forth in myLetters Patent dated August 21, 1.888, No.

printed may not be separated by extended intervening spaces; but whenthe wheels have heretofore been used in connection with keys arrangedupon a key-board and with intermediate actuating devices it has beennecessary to separate the wheels in consequence of the necessaryseparation of the numerous keys to enable them to be properlymanipulated. In order to obviate this defect, I arrange the wheels ofthe recorder in the desired proximity to each other and the keys of thekeyboard in their necessarily separated positions and employ anintermediate series of actuating devices diverging from the recorder tothe keys. Thus the rack-levers L, Fig. 3, are arranged in proximity tooperate each directly upon one of the wheels, while the connected leversB are separated at their ends,

so that the end of each lever will be directly under the series of keysD by which it is operated or controlled. By this means I am enabled tospread the keys upon the keyboard to any desired extent withoutseparating the printing-wheels.

It will be evident that if all the printingwheels J are at zero and anumber of the wheels are moved to set up a number to be printed, and thetypes or figures on said wheels brought in line with the cipher-typesupon the other wheels, the matter printed will consist of one or moreciphers preceding a number of figures in line. Thus if there are ninewheels and five of them are moved to bring certain figures into positionto print the number 92816, the line printed will. present thisappearance, 000092816. As the presence of the ciphers before the otherfigures is not only useless but confusing, I prevent the printing of anybut the figures required to represent the sum by such an adjustment ofthe wheels that no printing is effected from those representing a highervalue than the highest figure in the sum to be printed.

To lock both the printing and non-printing wheels in position, I use aframe M, Figs. 1, 4, and 5, sliding on a shaft M, parallel to the shaftK, said frame consisting .of two side pieces or arms 7c 702 and across-piece 7c, the latter carrying a feather e, extending into a slot 6in the shaft M, so that the frame will slide on and rock with saidshaft. The arm carries a rod i and the aim [t a rod i the rodsprojecting toward each other and their ends being nearly in the samevertical plane, the rod i being above the horizontal plane of the shaftK and the rod 17 below said plane, andso arranged that when the wheels Jare turned to the position shown in Fig. 2 and the frame M is rocked inthe direction of its arrow 1) to the position shown in Fig. 1 the rod 6Fig. 2, will contact with the shoulders of the opposite type-wheels andhold them in position to print, while the arm i will contact with theshoulders of the non-printing wheels and turn them to such an extent asto carry their type out of printing position and hold the wheels withthe spaces or notches in line with the printing type of the otherwheels.

It will be seen that by sliding the frame M to such a position as may berequired, any desired number of wheels may be cut out of printingposition.

It is desirable that the frame M shall move automatically, and after anynumber has been set up by the wheels be set to such a position that thenon-printing wheels will be cut out of action when the frame is stopped.Different means may be employed for effect ing this result, dependingupon the character of machine in which the recorder is employed, onemeans being illustrated in the drawings. Thus a spring S, Figs. a and 5,tends to draw the frame M toward the right, and a flexible band or strapN passes around a guide-pulley and is connected with any vibrating partof the machineas, for instance, with a plate P, connected with one ofthe side levers E, so that the frame will be drawn fully to the leftafter each number has been printed. To the frame M at a. is pivoted apawl Q, having a long arm with a beveled end i and a short arm bent andformed into a pawl 1 adapted to engage with a rack m on the shaft M, theteeth of which are spaced to correspond to the distance between therack-levers L. The levers L have each a projection 01, Figs. 2, 4, and5, at the upper edge of the rack portion, so situated that when theparts are in the positionshown in Fi 5 the pawl Q will rest upon thesaid projections a and slide thereon as the frame is carried to theright. \Vhen one or more of the rack-levers (beginning at the right) aremoved back by the action of the keys, the projections n of suchrack-levers pass from below the pawl and allow the long end of thelatter to drop and the short end of the pawl to engage with one of theteeth of the rack m and prevent further movement of the frame.

The pawl Q does not immediately drop upon the movement of lever L, butwill drop while passing the opening made by the movement of said lever.The rack-teeth m on the shaft M are spaced to correspond with therack-levers L, so that when the projection F of the pawl Q. is allowedto drop in the opening made by the movement of one of the rack-leversthe end "i of the pawl Q will engage with rack-tooth in corresponding inposition to the rack-lever moved. If it is desired to print the amount10000, the fifth-rack lever, counting from the right, willbe moved. Itwill now be seen that as the pawl Q is carried to the right by themovement of the frame M the projection 2'7 will will drop on reachingthe space made by the movement of the sector-lever L, and the end i ofthe pawl Q will contact with the corresponding racktooth m By thismovement of the frame M the rod 1" is brought to a position to contactwith the first five recorder-wheels J and the rod i with the remainder.After a number has been printed the draft upon the strap N carries theframe M to its first position. The shaft M and its frame are rocked asthe parts reach their lowest position by means of any suitableconnection--for instance, by the contact of a projection 11 on one ofthe levers E upon the shaft 0 with an arm q, projecting from the shaftM. An arm R, carried by the shaft M and connected thereto by a stiffspring 13, which yields slightly when necessary, carries a. pawl R,having a shoulder to", which, when the arm R swings forward, engageswith a pin :0 on one of two arms T, secured to a rock-shaft T andconstituting a carrier for a platen '21.. A spring 711 lifts the platen,and the latter is depressed as the pawl R is brought in line with thearm R until a stop m on the arm strikes thepawl, when the latter will becarried from the pin 00 and the spring m will force the platen with aquick sharp blow against the type or against the paper. An inking-ribbonis carried by spools XV \V and passes under guide-plates and between therecorder and the platen.

The strip of paper to be printed passes be tween the feed-rolls V V, andto permit the ready detachment of the printed portion of the paper Iarrange a knife it, Fig. 1,upona rockshaft a having a handle U outsidethe frame of the machine, and there is a recess in the base-plate a ofthe machine, forming a transverse shoulder 10, against which the paperisbent by the descent of the knife, so that a smart pull on the projectingend of the paper will separate the same along the line of theknife-edge. I

The movement of the feedrolls maybe i111 parted by any of the wellknownfeed-operatin g devices, which need not be here explained.

\Vhen it is not desired to lock the printingwheels, but one red may beused, and the rod or rods may be carried by any suitable form ofcarrier.

I do not here claim, broadly, a movable bar combined with a series oftype-wheels to turn part of the series, so that only those to printshall be in printing position, as this constitutes the subject ofaseparate application for Letters Patent, Serial No. 279,800, filed July13, 1888.

WVithoutlimiting myself to the precise construction and arrangement ofparts shown, I claim 1. The combination, with the wheels of aprinting-register, of a rod supported by a carrier to travel past and toand from said wheels to move the non-printin g wheels out of printingposition, substantially as set forth.

2. The combination, with the Wheels of a printing-register, of a movablecarrier provided with two rods with their inner ends on about the samevertical plane arranged to contact with the printing-Wheels, one to holdthe wheels in printing position and the other to turn them out ofprinting position, substantially as described.

3. The combination, with the printingwheels, of rack-levers havingprojections n, sliding and rocking frame M, carrying rods 2' t pawlcarried by the frame in position to contact at one end with the saidprojections, and a rack arranged to be engaged by the other end of thepawl, substantially as described.

4. The combination, with the printingwheels, of a carrier carrying theplaten, a

spring arranged to move the carrier toward the printing-wheels, and amovable arm or pawl arranged to contact with and force out the saidcarrier and to then move out of engagement therewith, substantially asset forth.

5. The combination, With the printing- Wheels and feed-rollers, of aplate having a transverse shoulder 20 and a knife to, movable to andfrom said shoulder, substantially as set forth.

6. The combination ofindependently-movable record-wheels arranged sideby side in
